Pećina Vjetrenica (Vjetrenica Cavern) is located at the western end of Popovo polje. From the cave entrance the visitor has a very nice view on Popovo polje, with the typical shape of a flat fertile floor and bare, steep limestone hills around.

The cave is gated by a massive iron bar gate and equipped with paths. Once there was also electric light, but it was destroyed during the war in the mid 1990s. The tourist section of the cave is mostly a huge passage, the first 500m of a river passage with very few speleothems. In several parts the cave floor is covered by rimstone pools, like in Pjati hall. In times of very wet weather the water rises in the inner part of cave (beyond 700m). Here are many streams and lakes, the largest one is Veliko jerzero (Great Lake), about 180m long and 1250m from the cave entrance. The colour of the rock is mostly reddish brown or red, caused by the red iron oxide.

The name of the cave is mentioned in the  Lexicon of Cave and Karst Terminology with Special Reference to Environmental Karst Hydrology on page 21. It is a geologic term which is translated (probably wrong) as blowhole. This cave is a blowing cave or wind cave, and that's what the name means. The cave system is rather huge, and so differences in temperature and differences in air pressure produce an air currency flowing in and out of the cave. The direction depends on the season, or better on the outside temperature. The wind blows rather strong, it can reach a speed of more than 10m/sec.

In 1584 Nikola Vitov Gucetic describes an unnamed cave in Popovo polje in Bosnia and Herzegovina, famous for strong wind at its entrance. This is very likely Vjetrenica Cave. This work is a comment on Aristotle's explanations of natural phenomenon according to the principles of natural philosophy. Gucetic tries to explain the origin of the wind by evaporation of the elements of the Earth caused by the Sun. He also noted that this wind is not observable deeper in the cave, but only at the entrance. He explained that by acceleration of air current in narrower parts of cave passages, similar to the acceleration of sea currents in narrow sea passages.

The cave was explored at the end of the 19th century by Joseph Riedel and C. Mihajlović. At the beginning of the 20th century J. Vavrović continued the exploration. The famous Bohemian geographer, zoologist and paleontologist K. Absolon and his collegue K. Paz made the most important discoveries between 1912 and 1914.

But the existence of the cave was known for a very long time, it was already mentioned in 1461 on the session of the Senat of Durovnik. Yet much earlier, Pliny the Elder (Gaius Plinius Secundus, AD 23-79) mentions in his work Historia naturalis a cave which is most likely Vjetrenica.

Today this cave is famous for its cave life. Vjetrenica Cave contains at least 80 types of stygobites and troglobites, making it one of the most diverse caves in the world. There are numerous scientific works about the cave. The most famous troglobiont (cave animal) in this cave is the olm (Proteus anguinus). And the cave also contains the bones of extinct animals, like cave bear (Ursus spelaeus). Most important was the discovery of complete skeleton of a leopard (Panthera pardus).

The name of the cave means Wind Cave, the reason for which is immediately obvious, when one arrives at the gated entrance. A howling gale at about 10.6°C emits from the cave, this flow being reversed in winter. When the summer temperature is higher than 30°C this comes as something of a shock to the system, and the cave supplied cloaks, so that visitors descend, looking like little pixies.
